Comparative study of allozyme polymorphism in the samples of Pinus sylvestris L. trees with different seed productivity

Korshikov I.I., Kalafat L.A.

Genotypes of 196 Pinus sylvestris L. plants from 10 natural populations of five Ukrainian regions have been determined using 19 polymorphic isozyme loci. Variability of quantity of full-grained, empty-grained and underdeveloped seeds in the cones of these plants has been studied. The basic indexes of genetic polymorphism were determined for 6 samples presented by 18-19 trees with high and low productivity of the full-grained, empty-grained and underdeveloped seeds. The maximum amount of rare alleles and genotypes as well as the highest heterozygosity (Ho = 0,285) were typical for the sample of plants with the maximum quantity of empty-grained seeds in the cones.
